The company made its decision a day after Jones accosted a CNN reporter, Oliver Darcy, on Capitol Hill, and livestreamed the encounter through Periscope, which Twitter owns.

Jones and InfoWars are notorious for spreading conspiracy theories and other demonstrably false information, including the idea that the Sandy Hook massacre was a hoax, and that the victims of it were child actors. Some of the parents of the victims have sued Jones for mental and emotional distress.

Later, he found Darcy outside a room where Dorsey was to appear before the House Energy and Commerce Committee.

Darcy’s reporting had previously raised questions about tech companies’ rules and statements about their battles against misinformation, and whether those were consistent with their allowing Jones and InfoWars to use their platforms. For example, after Dorsey himself tweeted that Twitter was not banning Jones like its counterparts had because “he hasn’t violated our rules,” an investigation by Darcy led to Twitter admitting that in fact at least seven tweets had broken its rules.

Jones shouted at Darcy for more than ten minutes, accusing him of being in favor of censorship and insulting his appearance, comparing him to “a rat” and told Darcy he was “evil-looking.” Jones was live on Twitter’s Periscope service the whole time.
